Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing having a front opening and having a groove formed in a rear wall thereof and extending rearward and extending in the vertical direction of the vehicle body. The present invention relates to a vehicle lamp having a reinforcing rib extending in a direction. 2. Description of the Related Art Conventionally, as such a vehicular lamp, for example, as shown in FIGS. 3A and 3B, a rearward opening is provided on a rear wall 1b of a housing 1 having a front opening 1a. A groove 1c extending in the vertical direction of the vehicle body is formed, and a plurality of reinforcing ribs 1d extending in the horizontal direction are formed in the groove 1c. In the figure, reference numeral 2 denotes a lens for closing the front opening 1a, and reference numeral 3 denotes a sealing material provided in an engagement groove 1e opening on the front side of the housing 1 and contacting the leg 2a of the lens 2. The illustrated groove 1c is located on one side edge (inside the vehicle body) of the housing 1 and extends from the upper edge of the housing 1 to the other side edge (outside the vehicle body). The water droplets formed and attached to the peripheral edge (excluding the lower edge) of the housing 1 are guided downward by the groove 1c. [0004] In the vehicle lamp constructed as described above, the water droplets guided to the groove 1c are temporarily reinforced as shown in FIG. 3 (C). Rib 1
d is drained downward after the water droplets W have accumulated on the upper surface of the vehicle body d. For example, when a vehicle lamp is mounted on the trunk lid at the rear of the vehicle body, the trunk remains with the water droplets W accumulated on the upper surface of the reinforcing rib 1d. When the lid is opened, there is a problem that the water droplets W drop into the trunk room. When the housing 1 is injection-molded,
Due to the presence of the reinforcing ribs 1d, there is a difference in cooling rate from the surroundings, and there is also a problem that sinks are easily formed on the front side of the rear wall 1b where the reinforcing ribs 1d are located. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to prevent the accumulation of water droplets by gently draining and guiding the water droplets while maintaining the role of reinforcement. It is an object of the present invention to provide a vehicular lamp capable of preventing generation of sink marks on the side. In order to achieve the above object, according to the first aspect of the present invention, a groove is formed in a rear wall of a housing having a front opening and extends rearward and extends in a vertical direction of a vehicle body. is, in a plurality of reinforcing ribs vehicle lamp is formed extending in the horizontal direction in the groove portion, wherein the multiple auxiliary <br/> strong ribs notches to lie displaced in the width direction is formed The gist is that it has been done. [0008] In such a structure according to the first aspect,
A groove opening rearward and extending vertically in the vehicle body is formed in a rear wall of the housing having a front opening, and a plurality of reinforcing ribs extending horizontally are formed in the groove, and are shifted in the width direction.
The notch is formed in the plurality of reinforcing ribs so as to be positioned at the right angles. An embodiment of a vehicular lamp according to the present invention will be described below with reference to the drawings. 1 (A) and 1 (B), a vehicle lamp 10 has a housing 11 having a front opening 11a and an engagement groove 11c formed in a peripheral portion of the housing 11 and opening on the front surface 11b side. It has a filled sealing material 12 and a lens 13 that integrally has a leg 13a facing the inside of the engagement groove 11c so as to contact the sealing material 12 and closes the front opening 11a. The rear wall 11d of the housing 11 has a rear surface 1
A groove 11f that opens to the 1e side and extends in the up-down direction of the vehicle body is formed. Further, the groove 11f plurality of reinforcing ribs 11g extending in the horizontal direction in, Ru <br/> have 11g ... are formed. Further, notches 11h, 11h,... Opening rearward are formed in the reinforcing ribs 11g, 11g,. In the above structure, the groove 11f is located on one side edge (inside the vehicle body) of the housing 11, and extends from the upper edge of the housing 11 to the other side edge (outside the vehicle body). The water droplets formed and attached to the peripheral edge (excluding the lower edge) of the housing 11
Guided downward by f. At this time, the notches 11h, 11h... Are formed at positions displaced in the width direction as shown in FIG. 2, so that water droplets guided in the groove 11f meander as shown by an arrow a. Is guided slowly downward. The notches 11h, 11h...
Water droplets are less likely to accumulate on the upper surfaces of the reinforcing ribs 11g, 11g,. Further, since some reinforcing ribs 11g also exist in the portions forming the notches 11h, 11h,..., As shown in FIG.
When the water drops pass through, the presence of the brakes is such that the water drops do not accumulate, so that the water drops can be guided more gently. Accordingly, since the water droplets adhering to the rear surface 11e are gently dropped without dropping, the load on the drainage structure on the vehicle body side is reduced, and the role of the reinforcing rib 11g as reinforcing is maintained. It is possible to prevent accumulation of water droplets, and furthermore, when forming the housing 11, the cooling rate of the reinforcing ribs 11g is increased, the difference from the surroundings is reduced, and the front surface 11b of the portion where the reinforcing ribs 11g are located
The occurrence of sink marks on the surface can be prevented. The notch 11h may be a hole-like notch formed near the rear wall 11d without opening backward. As described above, in the vehicular lamp of the present invention, the notches are formed in the reinforcing ribs, so that the guiding and drainage of water droplets can be performed while maintaining the reinforcing role. Gently, it is possible to prevent the accumulation of water droplets, and to prevent the occurrence of sink marks on the front side of the rear wall.
